Publication Type: Abstract Abstract: Whilst the primary goal of reintroductions has been the establishment of wild populations, there is increasing recognition of the potential for reintroductions to restore ecosystem function. The substantial range declines of the greater bilby (Macrotis lagotis) and the burrowing bettong (Bettongia lesueur) are thought to have had dramatic effects on ecosystem processes in the Australian arid zone because of their impacts on surface soils. We studied the effects of their reintroduction on litter and seed capture and soil nutrient levels, in comparison to two prevalent fossorial animals; the exotic European rabbit (Oryctolagus cuniculus) and the native sand goanna (Varanus gouldii). Bilbies and bettongs dug deeper and wider pits and excavated significantly more soil than rabbits or goannas. Litter and viable seed was restricted almost exclusively to the pits and soil in the pits had significantly higher levels of labile carbon and mineralisable nitrogen than surface soils. Compared with surface soils, bilby, bettong and goanna pits contained relatively more labile carbon than rabbit pits. The significantly greater soil excavation by bilbies and bettongs and the higher concentration of carbon in their pits, demonstrate that these reintroduced fossorial mammals play important roles in the creation of fertile patches. This study demonstrates that through habitat modification, reintroduced species can affect ecosystem function by enhancing resource retention at a local scale.
